Asbestos fibre dimensions and lung cancer mortality among workers exposed to chrysotile
OBJECTIVES To estimate exposures to asbestos fibres of specific sizes among asbestos textile manufacturing workers exposed to chrysotile using data from transmission electron microscopy (TEM) and to evaluate the extent to which the risk of lung cancer varies with fibre length and diameter. METHODS 3803 workers employed for at least 1 day between 1 January 1950 and 31 December 1973 in any of t...
متن کاملAsbestos fiber dimensions and lung cancer mortality among workers exposed to chrysotile
Objectives: To estimate exposures to asbestos fibers of specific sizes among asbestos textile manufacturing workers exposed to essentially pure chrysotile using data from transmission electron microscopy (TEM) and to evaluate the extent to which the risk of lung cancer varies with fiber length and diameter. Methods: 3803 workers employed for at least 1 day between 1 January 1950 and 31 December...
متن کاملCohort studies on cancer mortality among workers exposed only to chrysotile asbestos: a meta-analysis.
OBJECTIVE To determine whether there was excessive risk of cancer among workers exposed to chrysotile fiber alone by applying a meta-analysis technique. METHODS All data meeting the criteria of cohort studies on cancer mortality among workers exposed only to chrysotile were incorporated into meta-analysis. Pooled standardized mortality ratios (SMRs) and their corresponding 95% confidence inte...
متن کاملMortality and cancer incidence of workers exposed to chrysotile asbestos in the friction-products industry.
Three studies provide data on this topic. The largest was at the Ferodo factory in the U.K. There was no evidence of an overall excess in mortality from all causes, and in particular no increase in mortality due to lung cancer. Also, there was no evidence of any dose-response effect for lung cancer. There were 13 mesotheliomas but for 10 of these there had been exposure to crocidolite whilst wo...
متن کاملAsbestos, asbestosis, and lung cancer: observations in Quebec chrysotile workers.
One prospective epidemiologic study of asbestos cement workers with radiological small opacities has been cited as a rationale for attributing excess lung cancer to asbestosis. This approach could have considerable practical value for disease attribution in an era of decreasing exposure. However, a recent International Agency for Research on Cancer review concludes that the mechanism of product...
